AAsustor · Data Master

When a user configures the NAS to retrieve UPS status or control the UPS, a non-enforced TLS certificate verification can allow an attacker able to intercept network traffic between the client and server can perform a man-in-the-middle (MITM) attack, which may obtain the sensitive information of the UPS server configuation. This issue affects ADM: from 4.1.0 through 4.3.3.RKD2, from 5.0.0 through 5.1.0.RN42.
